Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment:
Referring to Fig. 1, the utility model embodiment comprises shell 1, arc control device 2, solenoid 3, handle 4, clip 5, armature 6, yoke 7, gusset piece 8, spring 10, snap close 11, latch spring 12, installation shaft 13, extension spring 15, stationary contact bar 16, movable feeler lever 17, guide 18, run-on tab 21.Parts such as handle 4, clip 5, armature 6, spring 10, snap close 11, movable feeler lever 17, extension spring 15 have been formed operating mechanism of the present utility model.
5 one-tenth U-shapeds of clip, the one end rotates and is inserted on the handle 4, and the other end rotates and is inserted on the movable feeler lever 17.
Snap close 11 is rotatably connected on the shell 1 by installation shaft 13, and it is provided with arch section 113, has lock buckling groove 111 on this part.One end of movable feeler lever 17 is sleeved on the arch section 113 of snap close 11, and cooperates with lock buckling groove 111.On snap close 11, also be fixed with and break away from post 112.
Armature 6 one ends can be connected on the yoke 7 rotationally, the other end be positioned at break away from post 112 near, it cooperates with disengaging post 112.Simultaneously, armature 6 is facing to the solenoid 3 that is fixed on the yoke 7, and under the electromagnetic action of solenoid 3, armature 6 can rotate.Spring 10 1 ends are fixed on the armature 6, and the other end is fixed on the yoke 7, and 10 pairs of armature 6 of spring play a part to reset.Be fixedly connected with bimetal leaf 14 on yoke 7, be welded with flexible connection 20 on the bimetal leaf 14, flexible connection 20 is welded on again on the movable feeler lever 17.Bimetal leaf 14 cooperates with snap close 11.Flexible connection 20 can the employing copper cash.
In the present embodiment, left plug 19 is connected with solenoid 3 by connecting plate 8: connecting plate 8 is connected with solenoid 3 spot welding, is fixedly connected with left plug 19 on connecting plate 8.Solenoid 3 is connected with yoke 7.Connecting plate 8 can be an integral body with left plug 19.
During use, left plug 19 and right plug 22 are injected in the pedestal.Upwards stir handle 4, in handle 4 rotation processes, clip 5 moves to lower half circle with the junction of handle 4 by the upper semicircumference that is positioned at handle 4 rotating shafts, clip 5 moves forward, driving movable feeler lever 17 moves forward, in this process, an end of movable feeler lever 17 is connected in the lock buckling groove 111 of snap close 11 always, plays the effect of the rotation axis and the strong point again.When upwards stirring handle 4 to extreme position, clip 5 with handle 4 fastenings at this extreme position.In this position, movable feeler lever 17 contacts with stationary contact bar 16, and left plug 19, solenoid 3, yoke 7, bimetal leaf 14, flexible connection 20, movable feeler lever 17, stationary contact bar 16, right plug 22 contact successively forms path, and circuit is connected.
Have the protection of short circuit instantaneous trip and two kinds of defencive functions of long delay dropout protection during use.
The protection of short circuit instantaneous trip: when being short-circuited situation, the electric current moment increase that left plug 19 feeds is a lot, and the electromagnetic field that solenoid 3 produces increases much thereupon, and the iron staff in the middle of the solenoid 3 produces enough big magnetic force, and suction moving armature 6 rotates.Armature 6 runs on rotary motion trace and breaks away from post 112, drives disengaging post 112 and moves, and breaks away from post 112 drive snap closes 11 and rotates.Because lock buckling groove 111 is positioned on the arch section 113 of snap close 11, after snap close 11 rotated, an end of movable feeler lever 17 and lock buckling groove 111 broke away from, and movable feeler lever 17 has not had the strong point, and separate with stationary contact bar 16 under the effect of extension spring 15 loosening back, and circuit disconnects.
The long delay protection of threading off: bimetal leaf 14 heatings are to snap close 11 direction deformation, push snap close 11 after being deflected into to a certain degree, and snap close 11 rotates, and movable feeler lever 17 separates with stationary contact bar 16, the circuit disconnection.
In addition, need to prove, the specific embodiment described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection range of the utility model patent according to the utility model patent.
